Xcode: Restore support for spaces in framework names

In commit ce2dee9e5b (Xcode: Don't add framework as -framework argument
in linker info list, 2020-09-28, v3.19.0-rc1~47^2) we split up the path
to a framework into the directory and framework name parts, but only
retained the quoting on the directory part.  Restore quoting of the
framework name.

Fixes: #21910
